- Toenex 7y agoThanks that was an interesting read. If the heat sink begins to dissipate are any structural risks to the network?
- Reason077 7y agoGiven that the trains are reported to be the largest sources of heat, the best solution in the long term will be new, more efficient trains. New drivetrain technology is already far more efficient, producing less waste heat, than the decades-old stuff still being use on most London Underground lines. In new trains, more powerful regenerative braking rather than friction braking will dramatically reduce heat produced from braking, for example. (It will mean less dirty air on the Underground, too!)
